HPG

HPG range direct high-pressure gas actuators use pipeline gas as the motive power source. These highly reliable scotch yoke quarter-turn actuators, available with either symmetric or canted yoke designs, are field-proven globally across a wide range of fluid power applications. Standard manual override uses an independent hydraulic cylinder which ensures separation of the hydraulic fluid from the pipeline gas and allows replacement of power cylinder seals without removing the actuator from the valve. An extensive range of options includes Rotork-designed high-pressure gas controls, pressure sensing valves and line break detection safety systems.
